Interestingly, yesterday's tweet about the NY/DC hyperloop was a major shift in Musk's tone from the flippant tweets of the past. Instead, it was classic Musk evangelical earnestness and hyper optimism that we are so used to seeing from him for all things Tesla related.
Which now makes me wonder, was the flippancy of Musk's past tweets, including the ironic name Boring Company, really reflective of Musk's semi-serious intentions, or a very calculated way for Musk to gradually disclose his very serious intentions?
What if Musk has been working seriously on this project for awhile and has worked out enough of the engineering and financial hurdles to make this a very serious endeavor. But before he's ready to seriously announce it, he needs to dig some tunnels and have some preliminary discusssions with govt officials, and he knows he can't possibly do that in complete stealth. But he also knows that if he discloses such ambitious intentions seriously at such an early stage, he risks the kind of ridicule he had to endure in the early days of Tesla, multiplied many times over.
So he plays it very lighthearted, ambiguous,and it all seems off the cuff and the distracted plaything of a visionary. Until he has enough pieces in place to shift to serious evangelizing.
Perhaps all his initial cheekiness has been very calculatingly clever introductory PR?
